WASHER.

Specification of Letters Patent.

Patented. Oct. 2, 1906,

Application filed July 26,1905. Serial No. 271,312.

To all whom it may concern.-

, Be it known that I, J OHN RICHARD HUGHES,

a citizen of the United States, and a resident of Ohama, in the countyof Rio Arriba and Territory of New Mexico, have invented a new andImproved Washer, of which the followmanufacture, besides being light inweight,

strong and durable, and possessing the capacity for long and repeatedservice.

In the accompanying drawings, forming a part of this specification,similar reference characters designate similar parts in all the views,and in which Figure 1 is an outer face view of a washer embodying myimprovements and showing the application of the washer to an ordinarycotter-pin employed as a fastening for parts of a structure. Fig. 2 is ahorizontal transverse sectional view of the washer and cotter-pin,showing the parts fastened together by the latter in dotted lines, andFig. 3 is a vertical sectional transverse view taken substantially atright angles to Fig. 2.

Before proceeding with a more detailed description it may be stated that1n the form of my improvements herein shown I employ an ordinarycotter-pin for fastenlng together two or more parts of a structurehaving "leither movable or stationary relation to each other, and inconnection with the cotter-pin I employ a washer of special constructionso adapted to the said cotter-pin as to pre vent either bending,breaking, or undue wearing thereof from frictional contact therewith ofany of the parts of the structure with which my improvements may beassociated.

Reference being had to the drawings by the designating charactersthereon, 1 represents, for instance, an ordinary wheel-axle, on which isplaced or mounted in the usual manner an ordinary hub 2 (shown in dottedlines in Figs. 2 and 3) of a wheel, said hub having movable relation tosaid axle. The axle 1 is formed therethrough at a suitable pointbeyondthe hub with an opening 8, through which is inserted an ordinarycotterpin 4, the extremities whereof at one end are united by anordinary loop 5 and those at the other end being bent oppositely orlaterally at 6, so as to prevent the cotter-pin from working out of thesaid opening 3. This is acommon way of utilizing the ordinary cotter-pinas a fastening between parts of a structure but, as is well understood,the cotter-pin frequently becomes broken from different causesas, forinstance, undue friction thereon or .abrading contact therewith of somepart of the structure with which the same may be associated or else byforcible or striking contact therewith of external bodies. In order toovercome these disadvantages, as well as to increase the longevity ofsuch form of fastening for various purposes, I employ in connection withthe cotter-pin a washer 7, shown in the present instance as having acentral circular opening 8 to enable the washer to be placed over theaxle 1 prior to the insertion through the opening in the axle of thecotter-pin, such washer being provided with offsets 9, which projectfrom the outer face thereof at opposite sides of the opening 8 and whichare in alinement with each other and provided with openings 10,coinciding with each other diametrically of said opening. In applyingthe washer to the axle 1, for instance, the same is turned thereon so asto bring the openings 10 of the offsets 9 into alinement with theopening 3 extending through the said axle, and then the free extremitiesof the members of the cotter pin are inserted through all of the Saidopenings, after which said extremities are bent outwardly, as alreadyexplained, by which to prevent loss of the cotter-pin and to maintainthe desired operative relation of the said washer 7 to the saidcotter-pin.

The offsets 9 on theouter face of washer are formed by strikingupportions of the 'metal of the washer at the desired places thereof, bywhich to derive the object sought. As shown in the drawings, the offsetsare formed by slitting the washer on opposite sides of the Opening andat a suitable dis- .tance therefrom and then bending the mateperimeterof the washer with equal effect.

While the washer is intended more especially for use in connection withcotter-pins, it is apparent that the same is equally adapted for use inconnection with ordinary pins or bolts frequently employed as a meansfor uniting together different parts of various devices or structures.

Having thus described my invention, I claim as new and desire tosecureby Letters Patent 1. A washer having a central opening andprovided on opposite sides of the opening with slits, the materialbetween the slits and opening being bent outwardly to form aperturedofisets.

2. A washer provided with a central opening and having the material onthe opposite sides of the opening bent outwardly to form aperturedoffsets.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN RICHARD HUGHES.
